GLASS-TANK.

Specification of Letters IPatent. Application filed July 26, 1910. Serial No. 573,898.

To all wiwm it may concern:

Be it known that I, CHAnLns C. Ross, a

citizen of the United States of America,

residing at New Kensing'ton, in the county of Westmoreland and State of Pennsylvania,

have invented certain newvand. usefulf'Ilns rovements in Glass TankS, .91 Which -"tl1e ollowing is a specification,referencebeing had therein to the accompanying drawing,;-.

This invention relates to glass tanks for the'inanufacture of window glass and more particularly to the tank mechanism employed in making that class 'of sheet glass produced from a cylinder that is blown, capped, slit, and then spread to form a sheet.

The primary object of the invention. is to provide in a manner as hereinafter set forth, a novel means for maintaining molten glass in proper condition whereby a large quantity or batch can be carried, provision being made for a fresh supply of molten glass aftereach gathering.

In the drawings: Figure 1 is a longitudinal sectional view of a portion of the tank, showing the pot in elevation, partly broken away and partly in section. Fig. 2 is a horizontalsect-ional view taken upon the line.

2-2 of Fig. 1, and Fig. 3 is a plan view'of a portion of the tank.

The glass tank has a suitable foundation 1, side walls 2 and a roof 3, and this struc ture is adapted to contain the molten glass from which the cylinders are made. The greater part of the tank, particularly the burners for retaining the contents thereof in a molten and fluid condition is ofthe ordina ry form, and at the rear end of the tank, from which the molten glass is withdrawn, the foundation 1 is lower, as at 4 and provided with an angularly disposed opening 5 terminating in a waste pit 6. Upon the lower foundation 4 is placed a basin 7 having a central opening 8 in, communication with the opening 5, and arranged over the basin 7 is a gas burner 9 adapted to receive gas under pressure and retain the contents of the basin 7 in a molten and fluid condition, whereby the contents will flow into the waste pit 6.

Upon the foundation or floor of the tank 2 at the rear end thereof is arranged a trough 10 extending from one of'the side walls 2 to the oppositewall. This trough *is provided witht'two partitions- 11 having longitudinalf conical-shaped; openings 12 iformed'therein Adaptedtoclose said openfings are conicalshaped -.valves or lugs 13 carriedby...valve levers -14s exten ing upwardly through openin s '1'5%"provided therefor --in the roof3" of. etank. The valve levers 14. are, trunnioned"between. bearings the opening'15. The upper ends of the valve levers 14 are provided with double eye-bolts 17, said eye-bolts being connected by reupon the roof'3. The eye-bolts 17 are also provided with cables 20 passing through eyes 21, carried by the brackets 19, and it is only necessary to pull upon the cables 20 to open the valves and allow the contents of the trough 10 to pass from the tank 2.

by a semi-cylindrical spout 22 trunnioned in the side walls 2 of the tank at the rear end thereof, one of the trunnions- 23 extending through the side wall 2 and being provided with a crank .24. This crank is connected by a retra'etile'sprin'g 25 to a. pin 26, carried 24 is also connected to an operating cable 27, and when this cable is released the ten sion of the spring 25 is released and the spout 22 is tilted, the inner end of the spout being lowered by the opening 12 of the trough 10. The inner end of the spout 22 is prevented from raising above the outer mouth-piece 28 carried by the trough 10.

The two com artments shown in the trough 10 are deslgned for the accommodation of the two valves 13. The innermost valve is normally maintained in an open position as shown in Fig. 1. The use of two. compartments and valves is designed for the safety of the device and tank from being rendered entirely useless The innermost valve permits the outer valve being removed and renewed without closing down the operation of the tank and also the by the outer side of"thiwall' 2. The crank opening 12 of the trough 10 by a U-shaped,

Patented M... 21, 191a 16 mounted upon the roof 3'at the sides'of tractile springs 18 to brackets 19 arranged The contents of the trough 10 are received revents the 7 should anything happen to one of the valves.

. ed upon the higher p1t 6, and it is from this pit that the waste.

glass can be returned to the tank 2 and again reduced to a molten and fluid condition.

The tank and those parts thereof subjected to the action of molten lass are made of non-fusible material, as re-brick, fire-cla and metal.

The evel of molten glass within the tank 2 has beenindicated by the dot and dash line 29, and this level is maintained by the attendant of the tank, whereby glass will not overflow the trough 10.

Over the waste pit 6 is arranged an invertible pot 57 into which the inolten glass is discharged by the spout 2% The glass is gathered from the pot 57.
